Product Overview
The Epro PR6423/003-030+CON021 Eddy Current Sensor System is a non-contact displacement measurement assembly consisting of an 8 mm eddy current probe and a CON021 signal converter. It is mainly used for monitoring shaft displacement, vibration behavior, and mechanical condition of high-speed rotating equipment.
In industrial machinery, the relative position between the rotating shaft and stationary components directly affects equipment operating stability. The PR6423/003-030 probe measures shaft movement by detecting changes in the electromagnetic field, while the CON021 converter processes the probe signal and provides a standardized output for connection to vibration monitoring and protection systems.
This sensor system is commonly applied in turbine, compressor, generator, and pump monitoring applications where continuous and accurate displacement measurement is required.

Working Principle
The PR6423/003-030+CON021 uses eddy current technology to measure the distance between the sensor tip and a conductive target surface.
Measurement process:
Rotating Shaft → Eddy Current Probe → CON021 Signal Converter → Monitoring Module → Protection System
Operating sequence:
- The probe generates a high-frequency electromagnetic field around the sensor tip.
- When the shaft moves closer or farther away, the eddy current effect changes.
- The probe detects this variation and converts it into an electrical signal.
- The CON021 converter conditions and processes the signal.
- The monitoring system analyzes shaft displacement and vibration conditions.
This measurement method allows accurate monitoring without direct contact, making it suitable for continuous operation of critical rotating machinery.
